you can also add 'up' just before it and still make sense. In many

The rng schema for <controller> had been non-specific about which
types of controllers allowed which models, and also allowed the
num_queues attribute (since that hasn't been released yet, should we
rename it to "numQueues"?) and <master> subelement to be included for
any controller type. In reality, half of the models are allowed only
for type='scsi', and the other half only for type='usb', num_queues is
allowed only for type='scsi', and <master> only for type='usb'.
This patch makes a separate <group> for type='scsi' and type='usb',
with each group allowing only the appropriate model values, and
allowing num_queue and <master> only when appropriate.
<interleave> also hadn't been specified, forcing a specific order of
subelements, which should never be done. (Note that the <interleave>
had to surround the main element attributes that are in the <group>
subelements, due to one of the <group>s containing a subelement).
The recent qemu requires "0x" prefix for the disk wwn, this patch
changes virValidateWWN to allow the prefix, and prepend "0x" if
it's not specified. E.g.
qemu-kvm: -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,\
drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,wwn=6000c60016ea71ad:
Property 'scsi-hd.wwn' doesn't take value '6000c60016ea71ad'
Though it's a qemu regression, but it's nice to allow the prefix,
and doesn't hurt for us to always output "0x".

<driver name='qemu' type='raw' cache='none'/>
<source pool='default' volume='fc18.img'/>

node device driver names the HBA like "scsi_host5", but storage
driver uses "host5", which could make the user confused. This
changes them to be consistent. However, for back-compat reason,
adapter name like "host5" is still supported.
This introduces 4 new attributes for storage pool source adapter.
E.g.
<adapter type='fc_host' parent='scsi_host5' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/>
Attribute 'type' can be either 'scsi_host' or 'fc_host', and defaults
to 'scsi_host' if attribute 'name' is specified. I.e. It's optional
for 'scsi_host' adapter, for back-compat reason. However, mandatory
for 'fc_host' adapter and any new future adapter types. Attribute
'parent' is to specify the parent for the fc_host adapter.

This introduce a new attribute "num_queues" (same with the good name
QEMU uses) for virtio-scsi controller. An example of the XML:
<controller type='scsi' index='0' model='virtio-scsi' num_queues='8'/>

-device virtio-scsi-pci,id=scsi0,num_queues=8,bus=pci.0,addr=0x3 \
Split the "resource" define out into multiple smaller
defines, one for each type of resource tuning parameter.

The virsh(1) man page wasn't saying anything about the 'migrateuri'
parameter other than it can be usually omitted. A patched version of
docs/migrate.html.in is taken in this patch to fix that up in the man
page.
This enrichs HBA's xml by dumping the number of max vports and
vports in use. Format is like:
<capability type='vport_ops'>
<max_vports>164</max_vports>
<vports>5</vports>
</capability>

libiscsi provides a userspace iSCSI initiator.
The main advantage over the kernel initiator is that it is very
easy to provide different initiator names for VMs on the same host.
Thus libiscsi supports usage of persistent reservations in the VM,
which otherwise would only be possible with NPIV.
libiscsi uses "iscsi" as the scheme, not "iscsi+tcp". We can change
this in the tests (while remaining backwards-compatible manner, because
QEMU uses TCP as the default transport for both Gluster and NBD).

The 'trang' utility, which is able to transform '.rng' files into
'.rnc' files, reported some errors in our schemas that weren't caught
by the tools we use in the build. I haven't added a test for this,
but the validity can be checked by the following command:
trang -I rng -O rnc domain.rng domain.rnc
There were unescaped minuses in regular expressions and we were
constraining int (which is by default in the range of [-2^31;2^31-1]
to maximum of 2^32. But what we wanted was exactly an unsignedInt.
This plumbs in the XML description of iSCSI shares. The next patches
will add support for the libiscsi userspace initiator.

Qemu's implementation of virtio RNG supports rate limiting of the
entropy used. This patch exposes the option to tune this functionality.
This patch is based on qemu commit 904d6f588063fb5ad2b61998acdf1e73fb4
The rate limiting is exported in the XML as:
<devices>
...
<rng model='virtio'>
<rate bytes='123' period='1234'/>
<backend model='random'/>
</rng>
...
The native bus for s390 I/O is called CCW (channel command word).
As QEMU has added basic support for the CCW bus, i.e. the
ability to assign CCW devnos (bus addresses) to devices.
Domains with the new machine type s390-ccw-virtio can use the
CCW bus. Currently QEMU will only allow to define virtio
devices on the CCW bus.
Here we add the new machine type and the new device address to the
schema definition and add a new paragraph to the domain XML
documentation.

There is some controversy[1] on the qemu list on whether qemu should
have ever allowed arbitrary file name passthrough, or whether it
should be restricted to JUST /dev/random and /dev/hwrng. It is
always easier to add support for additional filenames than it is
to remove support for something once released, so this patch
restricts libvirt 1.0.3 (where the virtio-random backend was first
supported) to just the two uncontroversial names, letting us defer
to a later date any decision on whether supporting arbitrary files
makes sense. Additionally, since qemu 1.4 does NOT support
/dev/fdset/nnn fd passthrough for the backend, limiting to just
two known names means that we don't get tempted to try fd
passthrough where it won't work.
